圆底烧瓶

如果圆底烧瓶置于空烧杯中，则可屏蔽气流使反应进行平稳。

The reaction proceeds more smoothly if the round-bottom flask is shielded from draughts by being placed in an empty beaker .

在小型浮选槽和3连圆底烧瓶浸出实验的基础上，在实验型空气搅拌浸出槽中进行了用SO2浸出东湘桥地区氧化锰矿石2kg的实验。

Based on the results in small floating cell and in a series of three round bottom flasks , the experiments on the leaching of oxidized manganese ore using SO2 were carried out in an experimental pachuca tank .

It has a tray that may hold radius flask .

这个方法包括将蛋白质溶液在圆底烧瓶的瓶壁上冰冻，和在真空中让液体升华。

This method involves freezing the protein solution on the walls of a round bottomed flask and sublimating the liquid in a vacuum .

本文用三颈圆底烧瓶及比色法测定钻（Ⅱ）式交换树脂在不同浓度的氯化钙溶液中的交换扩散机理。

The ion exchange between cobalt (ⅱ) - form ion exchanger and calcium chloride solution was studied by using a three-necked flask as the reaction vessel and the rate of exchange was measured by the colorimetric method .
